Nerites are certainly the best snail to buy if you've got an algae problem.
1. They're absolutely adorable
2. They don't breed in freshwater
3. They're non-aggressive
4. 5 Nerites in a 10 gallon tank coated with algae will clean it up in about a week
5. Nerites are just....too....flippin....cute.....(you should see their teeny lil faces! And their eye stalks? FREAKING ADORABLE)
6. Nerites may poo a bit but not so much as to really pollute the tank
7. Nerites will nom the algae off plants but not eat the plants themselves (though sometimes they can't resist a nibble of water sprite or anacharis, but give them a break....they do so much for you, they deserve a treat ;)

AWWWWW YEEEEAAAAAH anyway just get a Nerite snail. I don't know, but I have a good feeling about them. They're just too awesome to describe. I almost love them more than bettas :O

I'd get a nerite smail or two
but right now my vehicle is in the shop and my husband is my only source of transportation. when he has time to relax, he will only stay home. there aint no way no how he is going somewhere. even if it is for only a few items at max and the destination is close to home. he aint moving his hard workn bum.

i think right now ill just keep on cleaning the algae off. and should it disappear naturally by the time i get my vehicle back, great, but if it is still there then ill try a nerite or two.
